C. He calls his name to the Cyclops even after his men beg him to
stay silent
Explanation:
The detail from the Odyssey that shows the pride and ability of Odysseus to be vain is the fact that he tells his real name to the Cyclops after they defeat him and sail away, he does that just to show off, and he puts his tripulation in danger because now the other cyclops will know who hurt their fellow cyclop friend and can look for revenge.
